Beyond universal behavior in the one-dimensional chain with random nearest neighbor hopping
Akshay Krishna, R. N. Bhatt
We study the one-dimensional nearest neighbor tight binding model of electrons with independently distributed random hopping and no on-site potential (i.e. off-diagonal disorder wi…
Floquet dynamics of disordered bands with isolated critical energies
Sriram Ganeshan, Kartiek Agarwal, R. N. Bhatt
We investigate the localization properties of driven models that exhibit a sub-extensive number of extended states in the static setting. We consider instances where the extended m…
Dimensional crossover of the integer quantum Hall plateau transition and disordered topological pumping
Matteo Ippoliti, R. N. Bhatt
We study the quantum Hall plateau transition on rectangular tori. As the aspect ratio of the torus is increased, the two-dimensional critical behavior, characterized by a subthermo…
Cooling arbitrary near-critical systems using hyperbolic quenches
Prahar Mitra, Matteo Ippoliti, R. N. Bhatt +2
We describe a quench protocol that allows the rapid preparation of ground states of arbitrary interacting conformal field theories in dimensions. We start from the ground sta…
Localization and transport in a strongly driven Anderson insulator
Kartiek Agarwal, Sriram Ganeshan, R. N. Bhatt
We study localization and charge dynamics in a monochromatically driven one-dimensional Anderson insulator focussing on the low-frequency, strong-driving regime. We study this prob…
Effects of large disorder on the Hofstadter butterfly
Chenggang Zhou, Mona Berciu, R. N. Bhatt
Motivated by the recent experiments on periodically modulated, two dimensional electron systems placed in large transversal magnetic fields, we investigate the interplay between th…
